check box helper not updating value in database Ruby on rails - html

Question

the checkbox helper isn't updating or inserting boolean values in the database.
A label has many attributes with values false as default and should become true when the checkbox is checked.but only the email attribute is being updated.
labelscontroller
def new
#label = current_user.labels.build
end
def create
#label = current_user.labels.build(label_params)
if #label.save
redirect_to #label
else
render 'new'
end
end
def labels_params
params.require(:label).permit(:name,:email,:avatar,:nick,:intro)
end
label/_form.html.erb
<%= form_for #label, :html => { :class => "form-horizontal label" ,multipart: true} do |f| %>
<div class="form-group", style="color: black;">
<%= f.label :name, :class => 'control-label col-lg-2' %>
<div class="col-lg-10">
<%= f.text_field :name, :class => 'form-control' %>
</div>
<%=f.error_span(:name) %>
</div> <div class="form-group", style="color: black;">
<%= f.label :email, :class => 'control-label col-lg-2' %>
<div class="col-lg-10">
<%= f.check_box :email %>
</div>
<%=f.error_span(:email) %>
</div>
<div class="form-group", style="color: black;">
<%= f.label :intro, :class => 'control-label col-lg-2' %>
<div class="col-lg-10">
<%= f.check_box :intro, checked: false %>
</div>
<%=f.error_span(:intro) %>
</div>
<div class="form-group">
<div class="col-lg-offset-2 col-lg-10">
<%= f.submit nil, :class => 'btn btn-primary' %>
<%= link_to t('.cancel', :default => t("helpers.links.cancel")),
labels_path, :class => 'btn btn-default' %>
</div>
</div>
